L2 LAN-2-LAN CDP issue

Post by ncc » Thu Oct 11, 2018 3:05 am

I setup a L2 LAN-2-LAN VPN and both end connected to Cisco Switch, it seems that the CDP could not retain, after the link has been established for some time, both end could not not find each other when using the "show CDP neighbors" Cisco command, is SoftEther blocking CDP?

I think SoftEther doesn't block the CDP packets.
Did you enable "DetectDormantSessionInterval"?
